Yeah…I like it as well. Unfortunately, the only way I can listen to it, since I haven't any of Biffy Clyro's music, is on YouTub - which isn't a source I can use to try and tab something. Otherwise, I would have tried to help out.
I need a WAV file of the song so I can pull it into Audacity, which allows me to slow it down, impose a low pass filter to let the bass stand out better….
The WAV file needs to be CD (or near) quality. If not high quality, I can't hear it well enough to tab…old ears, too much youthful loudness….
Follow on: it also needs to be a fairly simple bass line for me to be able to tab it. That's due to my being a fairly shitty bassist; I possess no talent as do Victor Wooten, Geddy Lee, Flea, Brian Bromberg, etc.
The moral of story: with sufficient trickery, anyone can tab!
